Do venture capitalists want their money back once the company gets established?

What happens if a VC funds a venture and the venture fails or does not make any money? Does the VC expect his/her money
back?
How about an angel?

Get rich quick schemes in the capitalist business world, (buyouts, IPOs, conglomerates, acquisitions, mergers, and the stock market), do not actually work. Remaining solvent does not actually exist within false economics capitalism.

Profit existing in the capitalist business world, or millionaires existing within capitalism, is pathological deception committed by the 21 organizations spying on the population with plain clothes agents, (with covert fake names and fake backgrounds).

Actual economics is the persons paying the monthly business loan payments of companies voting at work in order to control the property they are paying for.

Capitalism is the psychology of imaginary parents, false economics, and the criminal deception of employees that are paying the bills (including the stocks and bonds, or shares) of companies.

Anti-democracy republicanism is the psychology of imaginary parents, and false government.

For VC's the company they buy is a tool to get the best ROI.
Generally they want controlling interest. They buy companies with low debt, load up the company with new debt and use the proceeds to finance their purchase. The next decision is weather to liquidate the company or send in some hard nosed managers to squeeze the maximum profit from the company.
Eventually the company gets sold either as a going concern or in a liquidation, depending what gives the best return on their investment. The VC is not in business to make loans so there is no money to be paid back as you can see from the foregoing.
An angel investor is a different story. He'll give you money either for equity or as a loan, he expects to make money on his investment. his objective is to help the company get ahead and make money for himself at the same time.

The VC will be part owner of the Co, sometimes owning as much as 50% of the Co . They will have a say in how the Co is run. The VC will be watching his money VERY closely. The VC has to be convinced the Co will work upfront and will make money, an exit strategy!
An Angel is usually an individual investor who invests less than 100k in a startup. Same deal, will want to own up to 50% of the Co stock.
